Improved Joint for Furniture, &c., of which the following is a specification The object of my invention is the secure attachment of parts of-furniture or of other wooden structures together, as, for instance, the attachment of rails or cross-bars to the legs of a chair; and this object I attain in the manner which I will now, proceed to describe, reference. being bad to the accompanying draw;

, Figures 1, 2, 3, and 4 are sectional views In Figs. 1, 2, and 3, A represents part of the leg of a chair, and B part of one of the rails, These I secure together in the following man ner: I first bore an orifice, a, part way through the leg and insert therein -two metal'strips, DD, which are longer than the orifice isdeep, each strip being of the segmental form shown in Fig. 4,'so as to be adapted to the orifice and to the end of the rail B, having a projection,

and each strip b, at the end which bears against tlie'end of the orifice. serted the strips as duce between them a metal tool, D, of the same diameter as the end of the rail, and drive this tool to the end of the orifice, the result of whichis the driving of the projectionsfb of the metal strips into the wood. Afterwithdrawing the tool -I drive'the ends of the rail B into the space between the strips, which I secure to the said rail by a rivet, d, as shown in Fig. 2, or by screws.

I claim as my inventionp The combination of the strips D D, secured Having into the rail B by a rivetor screws, d, and having projections b, with the leg A, having an orifice, a, bored part way through' the same, all as set forth.

In testimony whereof I have signed my name to this specifieationin .the presence of two subscribing witnesses.
